That BS explanation would be great if you live in the same vacuum Apple executives live in.
Unfortunately, we live out here. In the real world.
There are 4" phones that last much longer than an iphone 5 with Android. And 4 inches is still a very small screen.
Not to mention the bigger screens from Samsung that dwarf the iphone and the battery lasts more than twice as long.
Then you'll say the phones are bigger so the batteries are bigger. But even if apple came out with a 5" phone, we will be back right here with people complaining that the battery life sucks.

My wife's sister just bought one. I think she charges it 3 times a day. All her and her friends talk about is ways to save battery. They had a theory that closing all the apps running all the time will significantly increase battery life, so you see all of them closing apps all day like maniacs, but they still have to charge it several times a day.
Maybe you're on WiFi all day or don't do much browsing and data intensive work, but iphone sucks on battery life.
There are guys with 4" Androids that go for days on 1 charge.
